Two articles on a similar topic. One is recent and the other is old. Both UX design related so don’t worry if you’re not interested in that kind of thing.

First, “Let Your Users Wait” by Tal Mishaly at UX Magazine. The upshot is that designers of interfaces should think more about time: about how users perceive it, about how the same period of time can seem to pass more quickly or more slowly depending on what the interface does, and even about how it can sometimes be useful to create delay.

Second, an oldie but goodie from four years ago: a cognitive teardown of the Angry Birds user experience by Charles Mauro in 2011. Reading the first article made me remember this one and how much I liked it at the time, so I dug it out of my bookmarks and read it again. I was hooked on Angry Birds back then, and some of Mauro’s comments about the game’s approach to response time management had a big impact on me:

In Angry Birds, it was possible for the programmers to have made the flight of the birds fast – very fast, but they didn’t. Instead they programmed the flight of the angry flock to be leisure pace as they arc across the sky heading for the pigs’ glass houses. This slowed response time, combined with a carefully crafted trajectory trace (the flight path of the bird), solves one huge problem for all user interfaces – error correction. The vast majority of software user interfaces have no consideration for how users can be taught by experience with the system to improve their performance.

I reinstalled Angry Birds recently to show to my 3-year-old son before recoiling in terror from its barrage of ads and—worse—dark patterns leading to shady in-app purchases. But despite all that I think there’s still a lot for interaction designers to learn from Angry Birds.

If you’re one of them (an interaction designer that is, not an angry bird) feel free to spend tomorrow morning playing Angry Birds. If your bosses ask you what you’re up to, tell them it’s research and point them to Mauro’s article.
